Directional hearing and sound source localization by fishes.
Journal of the Acoustical Society of America, 2018 Directional hearing may enable fishes to seek out prey, avoid predators, find mates, and detect important spatial cues. Early sound localization experiments gave negative results, and it was thought unlikely that fishes utilized the same direction ...
